WEATHER STRIP.

Application filed March 28, 1924. Serial No. 702,693.

The present invention relates to weather strips and an object thereof is to provide a strong and durable construction which may be used on casement windows and similar places for the purpose of excluding wind and moisture.

To this and other ends, the invention con sists of certain parts and combinations of parts, all of which will be hereinafter de scribed: the novel features being pointed out in the appended claim.

In the drawing:

The figure is a fragmentary perspective view of a casement window equipped with the present invention.

In this illustrated embodiment of the invention 1 indicates the side frame and 2 the sash which in a casement window is hinged at one vertical side. On the plane surface 3 of the frame adjacent the forward edge of said surface, a channel member at is rigidly secured. This channel member has its bottom wall fiat, and in one plane and its outer wall 5 of greater length than its inner wall 6. This outer wall also has an inturned flange 7 formed by doubling the metal from which the channel is formed so that a rigid flange 1s secured, not liable to be bent or deflected by ordinary use.

The sash 2 is formed with a longitudinal groove 8 which is of such a size that the channel member may be snugly received therein, the forward portion of such groove having a supplemental groove 9. Arranged on the sash 2 is a strip having a portion 10 on the front face of the sash, a rib 11 along one edge being received within a kerf or groove 12 in the sash and a U-shaped portion 13 along its other edge being re ceived within the supplemental groove 9 and opening outwardly so that the reinforced flange 7 on the channel member may be received therein. This U-shaped portion by lying in the supplemental groove 9 is protected against blows from its rear and, at the same time, is enabled to clear the free edge of the rearmost wall 6 of the channel member.

It will be noted that, with this arrange ment, moisture is prevented by the flange 11 from passing back of the strip 10, while the flange 7 by projecting into the groove formed by the U-shaped portion 18 prevents wind passing between the two members of the weather strip. Should any moisture work through the joint between the two members of the strip, then it will fall into the channel member 4, being prevented by the channel member 6 from passing into the building and flowing from the channel by way of the holes or drain openings lii: in the lower portion of the front wall of the channel.

What I claim as my invention and desire to secure by Letters Patent is:

In combination with a frame and a sash of a casement window, a weather strip comprising a channel member secured to the frame and having a front vertical wall flush with the front face of the sash, a cooperating piece secured to the sash, flush with the front wall of the channel member, and cooperating means on the channel mem her and the sash carried piece providing a weather proofing joint and embodying two flat horizontal abutting surfaces, one extending inwardly from the lower edge of the sash carried piece and from a point in line with the front face of the sash and the other extending inwardly from the front wall of the channel member and from a point in line with the front face of the sash.
